I am kind of new to Radiance, working with it for 2 months now, i am encountering the following problem:
I am calculating daylightfactor (DF) for rooms with the following steps:
- Creating the Radiance Geometry is done, checked it with the Rad Viewer
- All Geometry has the right material, checked it with the Rad Viewer
- Creating a Uniform Overcast Sky of 10.000 lx.
- Creating all calculationpoints en run Rtrace.exe to ghet results
Making the actual calculation for all points in the Room works Great, but only when the Windows/openings are at 1 side of the Room, when creating 2 openings at different sides (lets say North and South) the daylight only enters the Room from 1 side.
Even when the geometry has no Glass but only openings.
These setting I use for Rtrace.exe: -w -h -I+ -ab 5 -oov -aa 0.1 -ad 1024 -as 64 -ar 16
Anyone familiar with this problem and have a solution?
thanks in advance.
